Well Treatment Solid Chemical

摘要

A solid chemical delivery system for delivering chemicals to an underground formation. The solid chemical is formed bv dehydrating a precipitated silica matrix. Well chemicals are then introduced to the silica and form a tablet or pelletized chemical. The pelletized solid chemical is then delivered to the underground formation through the well bore with a proppant and well treatment fluid. This allows the well treatment chemicals to be released over time.

主权项

1. A method for delivering a liquid chemical agent in a solid form, the method comprising:
providing an amorphous silica matrix formed to carry a well treatment chemical within the matrix to form a solid chemical wherein the amorphous silica matrix has a porosity exceeding 50 percent by volume; providing an enzyme proximate the amorphous silica matrix; and pumping the amorphous silica matrix, a proppant, nd a well treating fluid into the wellbore; wherein the solid chemical is circulated within the well using the well treating fluid and provides a metered release of the well treatment chemical therefrom.
